A DC power supply circuit including an input stage having a bridge configuration and having static switches and respective diodes, the circuit being connected to the primary winding of an isolating transformer, the secondary winding thereof being in turn connected to a diode bridge connected to an output stage. The power supply circuit includes a DC voltage conversion means. The DC voltage conversion means has an operating frequency that is synchronous and double with respect to the operating frequency of the input stage having a bridge configuration, the stabilization of the output voltage can occur without varying the frequency, and all the static switches always switch in soft-switching conditions. |
